House Harroway of Harrenhal is an extinct noble house from Harrenhal in the riverlands. According to semi-canon sources they blazoned their arms with per bend sinister orange and black rayonne, a castle counterchanged.[1]Lord Harroway's Town is named after a former lord of the house.[2]

In 44 AC House Harroway was wiped out by Maegor after Alys had given birth to a monstrosity. Maegor's third wife, Queen Tyanna, had convinced him Alys had been having affairs, and provided the names of the men she had supposedly been sleeping with. This resulted in the execution of every Harroway Maegor could find, both in King's Landing, Harrenhal, and Lord Harroway's Town.[5][6]
